Sabrina, Really, it doesn't have to be so all fired technical. Some people make out like it's rocket science but it really isn't. I never sprouted my daylily seeds before planting them. I also never dried them or held them over on purpose before planting them. I got a pod, the pod got ripe & began to split open, I took the seeds and planted them directly into a pot that contained part potting soil (whatever I had around no matter the age of it), part sand (out of my yard), part vermiculite and part pearlite. The proportions were what I "felt" was right for my growing conditions -- sort of like when you cook - you often cook by feel and throw in a dash of this, a pinch of that, you get the idea, so the same thing with soil. It is my opinion that you don't have to have any special germinating soil or mix nor have sterile soil. I was in zone 10 Florida, so very hot & humid & sunny. I would plant the seeds directly into my soil mix, water & leave them sitting in the sun. I would water according to when it began to dry out which might be twice a day or once every 2 days or whatever depending on what the weather did. I didn't keep written records but I will estimate I had about 80% germination rate if not higher. I treated seeds that were sent to me the same way. I got them, I planted them.
I agree with Natalie. This is supposed to be fun. Just relax & have fun with it. Find out what works for YOU in your area under your growing conditions. If one day you decide you want to become a hybridizer then you can keep logs of exact measurements, temperatures, daylight hours & anything else you think might make a difference and make a science of it. Until that time just ENJOY it! Have FUN with it! Do it YOUR way. RELAX.
